Working Principle of Optical Gas Imaging
Optical gas imaging utilizes infrared technology to visualize invisible industrial gases. Gas absorption at specific wavelengths creates infrared radiation differences between the gas and background. The detector's narrowband filter receives infrared bands near gas absorption peaks, converting radiation differences into visible infrared images.
